+
+pyblosxom2wxr.sh is a shell script that migrates content from PyBlosxom
+to WordPress. It converts PyBlosxom posts and comments into a WXR
+(WordPress eXtensible RSS) file that can be imported into WordPress.
+
+Notes:
+
+- The post file extension is hard-coded to .txt, since that’s what
+  PyBlosxom expects.
+
+- Pages are supported as well as posts. pyblosxom2wxr assumes that post
+  filenames start with the date, in YYYY-MM-DD format, e.g.
+  2010-07-28_my_post.txt. Files without a prefix in that format are
+  assumed to be pages. (This is hard coded but would be easy to change.
+  Search for the date_re variable.)
+
+- The filename is used as the WordPress post/page GUID, and the first
+  line of the file is extracted and used as the title. The second line
+  is assumed to be blank. If your files don’t follow that format, you’ll
+  want to preprocess them or tweak the script.
+
+- Categories are not (yet) supported. All posts and pages are assigned
+  to the “uncategorized” category in WordPress.
+
+- WordPress limits import files to 2MB, but pyblosxom2wxr can generate
+  output files larger than that. If that happens, you can split it
+  manually or with a tool like ChoppedPress.
+
+- By default, the last modified time of post and page files is used as
+  their timestamp. However, if you have a timestamps file from the
+  hardcodedates PyBlosxom plugin, it will be used instead. The default
+  path is ../timestamp; you can customize this by editing the
+  timestamp_file variable in the script.
+
+- If you use Markdown or another markup language where line breaks and
+  whitespace are meaningful, you’ll want to apply this patch to the
+  WordPress importer.
+
+- pyblosxom2wxr doesn’t assign post ids. It omits <wp:post_id> elements
+  in the output file. This makes WordPress allocate post ids itself.
+
+- However, WordPress won’t allocate comment ids itself, so pyblosxom2wxr
+  has to do that and populate them in <wp:comment_id> elements. This
+  means that importing a WXR file generated by pyblosxom2wxr may
+  overwrite any existing comments!
+
+- If you use PyBlosxom’s compact_comments.sh, comments imported from
+  -all.cmt files may not be ordered by date. See my page on extracting
+  compacted PyBlosxom comments for a workaround.
+
+Known bugs:
+
+- Posts with more than 256 comments are not supported well. Only the
+  last 256 comments will be imported, and will likely be ordered wrong.
+  See the TODO near the end of the script.
